It happened because of the EU referendum. Perhaps you haven't heard about this yet, because you are very, very lucky.

The tl;dr of the EU referendum is that next week British people are voting on whether they want the UK to leave or remain in the European Union. The EU currently has 28 member states, most of which share a currency and freedom of movement.

Here's the EU and UK flags fluttering in the wind. There, you're up to date. Now let's get to the embarrassing bit.

So. Today the two sides in this debate – "Leave" and "Remain" – GOT IN A BUNCH OF BOATS AND TOOK TO THE WATER. THEN LEAVE SHOT REMAIN WITH WATER HOSES IN THE MIDDLE OF THE THAMES WHILE REMAIN BLARED TERRIBLE MUSIC.

It all started when a flotilla of pro-Leave craft – mostly fishing vessels – gathered at sea and then steamed up the Thames Estuary towards London, in order to make a point.

"Brexit" stands for "British exit" from the EU. Pro-Brexit is the same as pro-Leave.

Of course, the pro-Remain side would not stand for this incursion into their territory. So naturally they sent their own boat with former Boomtown Rats singer and prominent philanthropist Bob Geldof in it, to harrass the oncoming Leave fleet.

War is hell.

Here's a pro-Leave fishing boat. Lots of people in the fishing industry think we should leave the European Union, which regulates what they can and can't fish.

That's why they're spraying this Remain boat with hoses, like playful friends at a fundraising carwash, except if the friends hated each other and thought their friendship was being over-regulated by faceless European bureaucrats.

And here we have another one of the pro-Leave boats, bearing a sign expressing concern about the threat of the EU to British sovereignty.
